This are the sketches that artist Brian Lai drew that, when a photo of them is inverted, reveal Wolverine. Why always Wolverine? Man crush. And can you blame him? The man knows how to scratch a f***ing back. I make similar sketches, except you have to look at them in a mirror to see them. Check it out -- what do you see? "The same penis as before, but in a mirror." Pretty amazing, right? I bet you're wondering how I did it.

Keep going for another one and a video of how Brian does it.

Thanks to Rich, who always inverts all the photos he takes at art museums to see if he can find any Da Vinci codes hidden in the paintings.
